Key Features
-
Small-flow oriented design: With nominal flow of 10-15 L/min, it is specially adapted to small and medium-sized hydraulic systems, featuring low energy consumption and high matching degree with small executive components.
-
Precise commutation control: Stable spool movement and fast response speed, which can accurately control the flow direction of hydraulic oil, meeting the precise control needs of precision hydraulic equipment and reducing system energy loss.
-
Compact and practical structure: Small volume, modular or integral design, easy to install and maintain, suitable for equipment with limited installation space; Low-leakage sealing design ensures stable operation of the hydraulic system for a long time.
Process steps：
Customer inquiry: Customers will make inquiries before placing an order to understand product details and communication needs.
Quotation: According to customer needs, provide a formal quotation, including the name, model, quantity, delivery time, payment method, etc. of the goods.
Order confirmation: After the customer confirms the quotation, a formal purchase order will be placed.
Confirm the delivery time: communicate the delivery time with the production department, inform the factory of the order details, and arrange the production plan.
Sign an export contract: After the two parties confirm that it is correct, sign an export contract to establish a trade relationship.
Implement the letter of credit (if applicable): If the payment method of the letter of credit is used, the customer needs to be urged to issue the certificate and review the contents of the letter of credit.
Export stocking: According to the requirements of the contract and the letter of credit, arrange production, purchase raw materials and packaging, and prepare the goods.
Chartering and booking: Contact the freight forwarder to make a booking and arrange the transportation of goods.
Export inspection: Apply to the quality inspection department for export commodity inspection and provide relevant documents.
Apply for a write-off slip: apply for a write-off slip from the foreign exchange management department for subsequent foreign exchange write-off.
Export declaration: Declare exports to the customs and provide documents such as power of attorney for customs declaration, customs declaration form for export goods, commercial invoice, packing list, etc.
